Cadillac Gage Turrets Descriptions 90 mm Turret It is a two-man turret fitted with a 90 mm Cockerill Mk III gun or MECAR 90 mm gun, a coaxial 7.62 mm machine gun and a commander's ring mount with a pintle-mounted 7.62 mm machine gun. The turret can be rotated 360 degrees under power at speeds of up to 30 degrees per second and the 90 mm gun can be elevated from -8 to +28 degrees at up to 30 degrees per second. Dual controls allow either the gunner or the commander/loader to operate the turret and fire the main armament. Emergency mechanical hand-operated controls which can be used if the electro-hydraulic controls are disabled. The turret is fitted with interior lighting and an extractor fan. The turret has external vision by means of three direct view blocks, a commander's periscope mounted in the machine gun ring mount that provides 360 degree rotation and a gunner's periscope with a x8 monocular and a x1 periscope with a projectile graticule. For night surveillance a 200 mm, 500 000 candlepower white light spotlight is mounted coaxially with the 90 mm gun. The turret armour will defeat 7.62 mm AP projectiles at zero degrees obliquity and point-blank range. Front turret armour is capable of defeating 14.5 mm projectiles fired from a range of 500 meters. The turret is provided with a stowage basket at the rear and smoke/ fragmentation dischargers can be fitted if required. 76 mm Turret It is a two-man turret fitted with a British 76 mm L23A1 gun, a coaxial 7.62 mm machine gun and a commander's ring mount with a pintle-mounted 7.62 mm machine gun. The turret can be rotated 360 degrees under power at speeds of up to 45 degrees per second and the 76 mm gun can be elevated from -10 to +30 degrees under power at up to 45 degrees per second. Dual controls allow either the gunner or the commander/loader to operate the turret and fire the main armament. Emergency mechanical hand-operated controls which can be used if the electro-hydraulic controls are disabled. The turret is fitted with interior lighting and an extractor fan. The turret has external vision by means of three direct view blocks, a commander's periscope mounted in the machine gun ring mount that provides 360 degree rotation and a gunner's periscope with a x8 monocular and a x1 periscope with a projectile graticule. For night surveillance a 200 mm, 500 000 candlepower white light spotlight is mounted coaxially with the 90 mm gun. The turret armour will defeat 7.62 mm AP projectiles at zero degrees obliquity and point-blank range. Front turret armour is capable of defeating 14.5 mm projectiles fired from a range of 500 meters. The turret is provided with a stowage basket at the rear and smoke/ fragmentation dischargers can be fitted if required. 25 mm Turret The turret is of all-welded steel construction providing the crew with complete protection from small arms fire and shell splinters. The commander sits on the left from the gunner on the right, both with a single-piece hatch cover opening to the rear. Main armament consists of a McDonnell Douglas Helicopters 25 mm M242 Chain Gun with a 7.62 mm M240 machine gun mounted coaxially with the main armament and a similar weapon mounted on the turret roof for anti-aircraft defense. Turret traverse and weapon elevation are electro-hydraulic with manual controls for emergency use. An automatic deck clearance system is provided with power override facilities. The weapons are fired electrically but can be fired manual in an emergency. As an option, full gun/ turret stabilization is available. The gunner has an M36E1 day/ night sight and the commander has eight periscopes for all-round observation. As an option, the commander could have six periscopes and an M36E1 day/ night sight. Standard equipment includes a turret ventilation blower and a 500 000 candlepower spotlight. 20 mm Turret It is a two-man armoured turret armed with a Rh 202 20 mm automatic cannon, a coaxial 7.62 mm machine gun and a commander's ring mount with pintle mounted 7.62 mm machine gun. The turret can be rotated 360 degrees under power at speeds of up to 60 degrees per second and a minimum smooth tracking rate of 1 mil per second. The 20 mm gun can be elevated from -8 to +60 degrees at up to 40 degrees per second. Dual controls allow either the gunner or the commander to operate the turret and fire the main armament. Emergency mechanical hand-operated controls which can be used if the electro-hydraulic controls are disabled. The turret is also equipped with a turret ventilating blower, an emergency firing trigger for the cannon and a rate controller which allows firing of one, two or four rounds per second or full automatic mode. For night surveillance 200 mm 500 000 candlepower spotlight is mounted coaxially with the 20 mm cannon. The turret armour will defeat 7.62 mm AP ammunition at zero degrees obliquity and point-blank range. 20 mm 1 Meter Turret (Mounted on Commando Scout) It is a one-man armoured turret armed with a Rh 202 20 mm automatic cannon and a coaxial 7.62 mm machine gun. The turret can be rotated 360 degrees under power at speeds of up to 60 degrees per second and a minimum smooth tracking rate of 1 mil per second. The 20 mm gun can be elevated from -8 to +55 degrees at up to 40 degrees per second. Emergency mechanical hand-operated controls which can be used if the electro-hydraulic controls are disabled. The turret is also equipped with a turret ventilating blower, an emergency firing trigger for the cannon and a rate controller which allows firing of one, two or four rounds per second or full automatic mode. For night surveillance 200 mm 500 000 candlepower spotlight is mounted coaxially with the 20 mm cannon. The turret provides all-round vision for the gunner by means of eight direct-view vision blocks, which allow for instantaneous 360 degree vision. The gunner's periscope is a x8 monocular sight and unity periscope with a projectile graticule. In addition to the main sight the turret is equipped with an external anti-aircraft sight. The frontal armour of the turret will defeat 12.7 mm AP projectiles at 425 meters the remainder 7.62 mm Ap at point-blank range and zero degrees obliquity. Twin/ Combination Machine Gun (1 Meter) Turret It is a one-man turret capable of mounting different configurations of weapons including twin 7.62 mm or twin 0.50 calibre machine guns and may also be equipped with a combination of 7.62 mm/ 0.50 calibre machine guns. The turret is manually rotated with power option available and can be traversed 360 degrees. The traverse mechanism incorporates a manual friction brake which is foot operated and a friction drag mechanism allows it to be rotated with a fixed position and the drag mechanism allows it to be rotated with a fixed resistance, enabling the gunner to lay on the target more accurately. The weapons can be elevated from -10 to + 55 degrees through a manual jack screw mechanism. Ammunition is fed to the weapons from standard ammunition boxes, eliminating the need for feed chutes and allowing for rapid reload. Additional ready ammunition may be made available if the turret is not equipped with radio sets in the turret bustle. Weapons are fired electrically, singly or in unison. In the event of an electrical failure they may be manually operated. The turret has a monocular M28C sight with a magnification of x1.5 which is driven by the movement of the turret cradle, ensuring correct sighting at all times. All-round observation for the gunner is by eight direct vision blocks mounted in the upper part of the turret. The gunner has an adjustable seat and the turret is provided with a single-piece hatch cover that opens to the rear and an extractor fan. A 500 000 candlepower searchlight is mounted coaxially with the right machine gun. 40 mm/ 12.7 mm Turret This one-man turret, a further development of the Cadillac Gage twin/ combination machine gun (1 meter) turret, is armed with a 40 mm Mk 19 Mod 3 grenade launcher on the left and a 12.7 mm (0.50) M2 HB machine gun on the right. The turret is of Cadloy ballistic steel armour, the gunner having an M27 periscope sight with magnification of x1 and x8, external anti-aircraft sight, eight vision blocks and a single- piece hatch cover opening to the rear. A 500 000 candlepower spotlight is mounted above the 12.7 mm M2 HMG and moves in elevation with the weapons. A bank of 4 66 mm electrically-operated smoke dischargers is mounted either side of the turret rear.
